plz help choose control room dimensions

fellas,

which of the following would give the best low frequency mode distribution?
19'5", 14'2", 8' - Everest handbook of acoustics
253.50", 182.50", 96" - Auralex Acoustics 101

or
RealTraps - Maximum Studio


-the first has less than 2500 cu.ft but closest pair of axial modes is 3.2 Hz between 29.1 and 216.7 Hz
-the second has about 2570 cu.ft
would the extra volume help with better ITDG values??

both are out of bolt's area, but since ceiling is only 8' there are not that many options to achieve more volume
and the bonello curve for the first is smoother than the second

-the third option has splayed side walls. and also utilizes the golden ratio.



your advice would be greatly appreciated

Nomad,

room #1 has holes in the LF spectrum (C3, G#2, & D2 does not have modal support) but passes the Bonello criteria
room #2 does not pass Bonello

What size is YOUR room?

If you build from ground up, you can do much better.
Cheers,
John

mr Brandt,

the height can go up to 8.2', breadth to 16' and length about 22'



its strange after months of research i am still asking the same question.
i really don't want to make up my own dimensions since it is all too complicated for me. so i looked for pre defined examples that matched as close as possible to my constraints.

i was going with what mr. Everest said on his book about the first room "While this cannot be represented as the best proportioning possible, this room, properly treated, will yield good sound quality"

and starting from ground up isn't really an option
thanks for your reply.

If that were my room I would not make it smaller just to improve the room ratio. Regardless of size the room will need to be treated properly.

That said if you are experimenting with room ratios this might help: RealTraps - ModeCalc

With the room that size I would not have splayed side walls. I would want as much volume as possible and then just treat the side walls to help with flutter.
